Description

Full palm backup pad and sole

Technical Field

The invention relates to the field of shoes, in particular to a full-sole supporting plate giving consideration to sports safety and sports efficiency optimization and a sole comprising the full-sole supporting plate.

Background

There are many factors that affect the best athletic performance of an athlete, such as the athlete's own talent, quality of strength, training program, and ideal athletic equipment. The design of sports equipment is generally aimed at preventing sports injuries and/or improving sports performance, and for the purpose of optimizing sports ergonomics, there are three main strategies for improving the functional balance of athletes in training and competition, according to the first law of thermodynamics and functional principles: (1) storing and recovering energy to the maximum; (2) energy loss is reduced to the maximum extent; (3) and (4) optimizing the muscle function.

In basketball, by analyzing the game of basketball, players have more than 20% of the game time in high intensity sports such as accelerated and decelerated runs or sprints (55 sprints and 97 runs), jumps (44) and various high intensity basketball motions (94), which subject the lower limbs to large external and internal loads. The ankle and foot of basketball players are the most injured parts (39.7%), so the choice of sports equipment is particularly important, especially the choice of basketball shoes, which should improve the sports performance of players while minimizing sports injuries.

Athletic shoe manufacturers often emphasize that their footwear products have the effect of enhancing energy storage and return, however, based on the limitations of current design technologies and the material properties used for midsole construction, athletic shoes are typically characterized by poor energy storage and recovery capabilities. Thus, when the foot contacts the ground, a large portion of the energy stored in the midsole may be dissipated or lost through heat, friction, and vibration, thereby reducing the athlete's athletic energy efficiency. Therefore, there is an increasing interest in studying the role of sole bending stiffness in improving athletic performance. The insertion of carbon fiber plates into the midsole and insole, to improve performance by optimizing shoe bending stiffness, has been examined in various motions emphasizing speed and force.

However, for basketball sports, it is considered that the composite full-palm carbon plate in the sole of the basketball shoe does not conform to the principle of sports safety, because the excessive rigidity increases the load of muscles and tendons of the lower leg, which is likely to cause sports injury, and therefore how to balance the rigidity brought by the carbon plate and the load of lower limb muscles, and optimize the sports efficiency is a problem to be solved urgently.

Detailed Description

For a better understanding of the objects, structure and function of the invention, the full-sole supporting plate and sole of the invention will be described in detail with reference to the accompanying drawings.

The full-sole supporting plate can be arranged in the sole, is preferably made of carbon fiber composite materials, can be elastically deformed along with repeated treading of the foot of a human body, so that energy of the foot when the foot falls to the ground is recovered, and is released again when the foot of the human body treads the ground, so that boosting force is provided for a wearer, the treading and stretching efficiency is improved, stress concentration is reduced, and sports injury is avoided.

Specifically, as shown in fig. 1 to 5, the full sole support plate of the invention includes a half sole region 10, a middle foot region 20 and a heel region 30, wherein the half sole region 10 corresponds to the half sole of the human foot, the middle foot region 20 corresponds to the middle foot of the human foot, the heel region 30 corresponds to the heel of the human foot, and the half sole region 10, the middle foot region 20 and the heel region 30 are connected in sequence to correspond to the full sole of the human foot. The half sole area 10 is arranged in a bending way towards the foot direction of a human body, the middle foot area 20 is arranged in a bending way towards the ground direction, and the heel area 30 is arranged in a bending way towards the foot direction of the human body; the upper surface of the full-palm supporting plate corresponds to one side of the human spine towards the front of the human body, the lower surface of the full-palm supporting plate corresponds to one side of the human spine towards the back of the human body, the bending radian of the half-palm area 10 corresponds to the physiological bending of the lumbar vertebra section of the human spine, the bending radian of the middle foot area 20 corresponds to the physiological bending of the thoracic vertebra section of the human spine, and the bending radian of the heel area 30 corresponds to the physiological bending of the cervical vertebra section of the human spine.

The full-palm supporting plate is designed by referring to the curvature of the spine of a human body, so that the sole can play a seesaw effect when an athlete runs at a variable speed and pedals and extends forwards in the process of effectively helping the exercise, particularly basketball exercises, the direction of ground reaction force is changed, and the forward movement of the human body is effectively promoted. Specifically, in order to convert the kinetic energy in the horizontal direction into the kinetic energy in the vertical direction, the heel of the foot of a human body is required to participate in 'braking' work during jumping, and factors influencing the braking conversion efficiency mainly comprise the magnitude and the direction of the ground reaction force in the vertical direction and the magnitude and the direction of the ground reaction force in the horizontal direction, and because the ground is usually horizontal, the magnitude and the direction of the force can be changed and adjusted by changing the interaction interface between the foot and the shoe and adjusting the sole structure; furthermore, after the "braking" phase of the run-up jump, the human foot may enter a pedalling and stretching phase, in which the ergonomics of the "winch mechanism" of the metatarsophalangeal joint may be affected by a number of factors, including also the interaction interface between the foot and the shoe and the structure of the sole. Therefore, according to the stress shielding effect, the boosting effect of the full-palm supporting plate can be effectively improved by extracting three physiological curvature radians of a lumbar vertebra segment, a thoracic vertebra segment and a cervical vertebra segment of a human spine (referring to the common physiological curvature value of a healthy spine) as the curvature radians of the full-palm supporting plate.

Further, as shown in fig. 2 and 5, an elastic structure is provided on the heel area 30 of the full palm support plate, which can improve the linear deformability and structural toughness of the heel area 30.

Specifically, the first hollow structure 32 in the heel area 30 is a single oval hollow; preferably, a single oval first hollow structure 32 is disposed on each of the first elastic plate 31 and the heel area 30, and the first elastic plate 31 and the first hollow structure 32 on the heel area 30 are disposed in mirror symmetry. This arrangement minimizes stress concentrations.

Further, as shown in fig. 2 and 5, the half sole region 10 of the full sole support plate is provided with an elastic structure, and the elastic structure can improve the linear deformability and the structural toughness of the half sole region 10. Specifically, the elastic structure in the palm region 10 includes a second elastic plate 11, and the second elastic plate 11 is bent toward the ground and connected below the palm region 10 to form a second deformation space between the palm region 10 and the second elastic plate 11. When the half sole region 10 bears the load, the half sole region 10 and the second elastic plate 11 can be elastically deformed through the second deformation space, so that the rigidity and resilience at the half sole region 10 are increased. Preferably, the second elastic plate 11 and the half-sole region 10 have the same curvature, and the second elastic plate 11 is arranged in mirror symmetry with the half-sole region 10.

Further, as shown in fig. 1 and 3, the front sole region 10 is provided with a second hollow structure 12, so that concentrated stress in the front sole region 10 can be avoided. Preferably, the second hollow structure 12 in the forefoot region 10 is a double-ellipse hollow, and a major axis of the ellipse hollow is obliquely arranged to be parallel to a moving track of a center of sole pressure in the forefoot region 10; second hollow structures 12 are arranged on the second elastic plate 11 and the half sole region 10, and the second hollow structures 12 on the second elastic plate 11 and the half sole region 10 are arranged in a mirror symmetry mode.
